Stephanocyclus differs from Cyclotella by the absence of a two-layered valve wall. Stephanocyclus differs from Cyclostephanos by the absence of marginal chambers.

Stephanocyclus contains species that were included with Cyclotella meneghiniana and its allies, including C. caspia, and C. quillensis. Many Stephanocyclus species, however, have not been formally transferred.

Stephanocyclus species are widely distributed in alkaline and saline inland waters.
